The opening credit sequence was filmed in Munich. The moment where Ilja Richter and Hans Kraus are holding the sign with the movie's title and the line "Have yourself a few nice hours, go to the movies" is filmed near the train station Karlsplatz in central Munich. The moment where Ilja Richter is imitating a singer and is holding the sign with the singers in this movie is filmed in front of the Bavarian State Opera which is also nearby.
The theme song "Musik, Musik - da wackelt die Penne" sang by the cast can be heard first after 50 minutes within the movie. Earlier the song was only heard in an instrumental version.
The castle "Seeburg" where the school is located is actually "Castle Ort" near the lake Traunsee in Gmunden, Higher Austria. It was built in the 10th century and rebuilt after a fire in 1626 to the way it looks like today. Today it is mostly a museum, a restaurant and a wine cellar.
